“…Thus, it should be solved depending on the types of electrical tomography system as described by Sun and Yang [19] for ERT and Lei et al [20] for ECT. As a result, based on references by Lionheart [18] and Sun and Yang [21], the sensitivity coefficient of a two-dimensional electrode pair for non-invasive ERT is based on Equation (1).…”

“…In the third category, there are systems composed by a single set of electrodes [17][18][19][20][21][22][23][24][25][26][27], i.e. integration of a single plane and a single array of sensors for a dual-modality ERT/ECT system.…”

“…integration of a single plane and a single array of sensors for a dual-modality ERT/ECT system. These systems can be built with internal electrodes [17][18][19][20][21][22] and external electrodes [23][24][25][26]. For both types of sensors in this category, integration of the dual modalities in a single plane and a single set of electrodes is achieved by using a voltage-excitation and current-sensing strategy with a 2-terminal sensing configuration.…”

Abstract-The concept of entropy as a measure of information has been extensively applied in information theory and related fields. The complex nature of information has resulted in some proposed entropy definitions. In image processing, the entropy concept has been used in developing thresholding techniques based on maximum entropy principles for image segmentation, enhancement and object detection purposes. In this article, entropy definitions are analysed to establish their relationship and after that evaluate their performance in image thresholding. Static simulated data from Electrical Capacitance Tomography measurement system for annular and stratified flows in multiphase hydrocarbons production has been used. Performance evaluation results of thresholding algorithms using Renyi entropy has shown to improve the measurements, particularly for stratified flow regimes. The improvement is solely based on the entropy definition, and it has been observed the introduced controlling parameters do not affect its performance. Renyi entropic thresholding algorithm is relatively robust as it is independent of the controlling parameter q and the grey level resolution. Therefore, there is the potential possibility of using Renyi entropic thresholding to improve measurements in hydrocarbons flow measurement using Electrical Capacitance Tomography measurement system.
